Flexible channel allocation using best Secondary user detection algorithm

Mobile computing is human-computer interaction by which a computer is expected to be transported during normal usage. The main problem in the existing system is the power allocation algorithm and the channel allocation problem for cooperative multiuser orthogonal frequency division multiplexing (MU-OFDM) cognitive radio (CR) systems. In the flexible channel cooperation, resource allocation is the serious problem. The primary user (PU) can transmit the data through the Secondary User (SU). Then through the number of SU s the data is transferred to the base station. The channel can be allotted based on the two algorithms, the optimal distributed bargaining algorithm and centralized heuristic algorithm. Then in the existing system, inflation attack is the severe problem. The inflation attack is overcome by implementing the Future Peak Detection algorithm. This determines that the PU can decide itself to transmit data through which SU. So the inflation attack problem can be overcome and the data is traversed to the base station with the full security.
